Medicine & HealthTue, 15 Mar 2011 17:03:41 ESTnews219427381Carotid artery stenting shown to be cost-effective alternative to endarterectomyResearchers determined that carotid artery stenting (CAS) with embolic protection is an economically attractive alternative to endarterectomy (END) for patients at increased surgical risk. The study, based on data from the Stenting and Angioplasty with Protection in Patients at High Risk for Endarterectomy (SAPPHIRE) trial, found that initial procedural cost was higher with CAS, but post-procedure hospital stay was shorter which significantly offset associated costs compared to END. Details of the study&#151;the first to evaluate the long-term cost-effectiveness of CAS versus END in stroke and heart attack prevention&#151;are published in the March issue of Catheterization and Cardiovascular Interventions, a peer-reviewed journal of The Society for Cardiovascular Angiography and Interventions (SCAI).http://phys.org/news218371101.html

Medicine & HealthTue, 23 Feb 2010 19:50:01 ESTnews186176188Study finds new stent improves ability to keep vessels open for dialysis patientsKidney dialysis patients often need repeated procedures, such as balloon angioplasty, to open blood vessels that become blocked or narrowed at the point where dialysis machines connect to the body. These blockages can impact the effectiveness of hemodialysis, a life-saving treatment to remove toxins from the blood when the kidneys are unable to do so. But a new FDA-approved stent graft can keep these access points open longer, reducing the number of procedures these patients may need, according to research from the University of Maryland published in the February 11, 2010, edition of the New England Journal of Medicine.http://phys.org/news185047647.html
